Week Ten: Road Trip to North Country

This week I got to spend even more time with extension agents in the field! I drove up to North Country to spend some time with Mike Hunter, a Field Crops Specialist with the CCE North Country Regional Ag Team. Mike led a field day that morning at some of his soybean herbicide plots. Although most weeds are still pretty well controlled by glyphosate, Mike is working hard to develop strategies for farmers to deal with the relatively new challenges presented by herbicide resistant weeds. Tall waterhemp, Palmer amaranth, and glyphosate-resistant marestail are all large threats to crop production in this region of New York State.

Marestail in soybean field

Mike took me out to a couple of farmer’s fields to look for possible signs of herbicide-resistant weeds. This soybean field has already been sprayed with glyphosate, but the marestail is is rampant! If the marestail goes to seed, it will be very difficult to control here for years to come.

Maintaining good relationships with local farmers is also an important part of Mike’s work. He has to be able to communicate the results of his own test plots along with other new science in a way that makes sense and is applicable to each farmer that he works with. One example of this is Reed Haven Farms. The farm produces around 1200 acres of crops to feed their dairy herd. Getting to tour their farm gave me an opportunity to see how technology and science can help farms of all sizes.

Alleyway and cows

At Reed Haven, most of the cows are milked by robotic milkers. This cuts down on long term labor costs and volatility, allowing the farmers to focus more on other management aspects of the farm. Pictured here, an alleyway has also been neatly swept by a robotic feed-pusher.

Using laser guidance to attach milk cups to the cow, the robotic milker lowers stress for animals and has helped the farm achieve low somatic cell counts. The cow is able to quickly and comfortably be milked out on her own schedule. Tons of data gets collected from each cow, including the number of chews per day as well as the amount of milk delivered from each quarter of the udder. I posted a video of the milker in action below. The farm currently has 3 milking robots, with the infrastructure in place to add 2 more milkers to their main barn soon.

Fighting a Losing Battle and Trying New Things

This past week, members of the Edgewood Farm team, along with myself, tackled the exciting job of hand pulling waterhemp from a field of snap beans.  Waterhemp is in the Amaranth family which also includes other commonly found pigweed species.  Because it is a relative of pigweed, it can often be difficult to distinguish between the different species, especially as seedlings.  As waterhemp matures it becomes a little easier to identify because mature plants tend to have glossy and elongated leaves.  You might be wondering why we had to pull it by hand.  Unfortunately, waterhemp is resistant to many of the herbicides on the market today and that surly seems to be the case here since it was unphased by last years and this year’s herbicide applications.  Left unchecked the waterhemp would quickly spread out of control because a single plant can produce upwards of one million seeds.

On a more exciting note, wheat harvest is finally under way in Western New York.  As a bit of an experiment, a field of wheat was intercropped with soybeans for the first time at Edgewood.  Instead of planting the wheat with a grain drill, as is conventionally done, they planted it with their twin-row planter.  Then in May, the same twin-row planter was used to plant soybeans in between the rows of wheat. Last Thursday, the combine headed to the field to harvest the wheat and it yielded surprisingly well considering how poor it looked earlier thus year (lots of winter kill and drowned wheat).  Even though I will be back in school when soybean harvest takes place it will be exciting to hear how they turn out.  I imagine I will see more cropping systems like this in the future from Edgewood if this goes well and on paper it looks like it will return the largest profit per acre of all their crops.

Week Nine: Work with Extension

Soybean field

This was one of my favorite weeks field-work wise. I got to drive out to meet with Jodi Putman, a Field Crop Specialist with the Northwest New York Dairy, Livestock & Field Crops Team. Jodi stays incredibly busy. She works full time with CCE as well as taking classes and doing research through a Cornell graduate student program. I got to hear her talk about some of the history behind sulfur availability in the United States as well as current soybean crop needs at the Musgrave field day earlier this year, so it was really exciting to see more of her plots in action.

Josh and Jodi and weeds

Jodi and Josh, the new Field Crops and Forage Specialist with the Southwest New York Dairy, Livestock, and Field Crops Program, also took the time to give me some weed ID lessons in the field. Sedges have edges!

We started out the day sampling soybean trifoliates to be tested for sulfur content. It is very important for crops to have the right balance of essential nutrients available to try and avoid literally any shortage during the growing season. If plants have the right amount of each nutrient available at the right time of the year, not only will yields increase but possible nutrient losses are also greatly decreased. If soybeans don’t have enough sulfur at key points in the growing season, even large amounts of other nutrients will not be able to be used by the crop.

To sample soybean trifoliates, we picked the youngest fully developed leaves off of the plant. We sampled around 20 plants per plot. There were 4 treatments and 4 replications, so in total we sampled over 300 plants in one field alone.

Jodi also took me out to a local farmer’s field to see some possible European Corn Borer damage. The farmer didn’t plant the field with Bt treated seed, so the corn was genetically vulnerable to ECB attack. This kind of scouting is a big part of Jodi’s job. The farmer needed help figuring out how much of the corn was damaged and whether or not it was worth using a chemical to treat the corn this late in the season. Although a lot of damage was already done, Jodi was able to give some advice to help avoid future infestation.

ECB damage

By scouting several sections of the field for damage, farmers and extension agents are able to determine the financial viability of chemical applications to control for pests like ECB.

After unrolling some leaves, Jodi uncovered this well-fed European Corn Borer. This told us that the farmer was correct in IDing the cause of the damage.

Week Eight: Field Day at Musgrave

Barley at the Musgrave field day

Several NMSP team members made the quick drive out the Musgrave Research Farm for their annual field day earlier this week. It was really exciting to see how scientists communicate the value of their ongoing projects with both other researchers and the general public. There were a lot of cool speakers and a great lunch featuring Cornell Chicken Barbecue Sauce.

Kernza growing with red clover

Pictured: Kernza®️ intercropped with nitrogen-fixing red clover. This trial aimed to see whether or not farmers could avoid using expensive nitrogen fertilizer while still harvesting a strong grain crop.

One of the most interesting plots was the full field of intermediate wheatgrass. This crop goes by the tradename Kernza® and is known for both its exceptionally large root system and its ability to perenially produce bread quality grain. This means that the need for tillage is greatly limited, and the long roots are believed to support healthy soil development even on marginal land. Unfortunately, low yields have been a large challenge with this crop. The trial at Musgrave found that the crop stand gets so thick after a few years of establishment that grain yield is limited by self-competition. The researchers were able to relieve some of this pressure by using strip tillage to lower the amount of plants per acre. This seemed to be very effective at increasing yield, but not to the point that Kernza® was competitive with wheat on a pounds-per-acre basis. However, Kernza® also provides high quality straw forage for livestock which could make it a suitable crop for farmers with land at risk for soil erosion. I will be very curious to see how researchers continue to develop these cropping systems in the future, especially if carbon marketing comes into play for American farmers.

Technology on the Farm

Hey everyone, welcome back!  Now that all the crops are actively growing my duties at Edgewood Farms, LLC has switched from helping with field work to primarily scouting.  With about 4,000 acres to be keeping an eye on, there is no shortage of work for me to do.  This might sound like a daunting task, but luckily, I have some neat technology to help me out.  I have two apps downloaded on my phone; the first is called Encirca, and the second is called Granular.

Encirca is a part of Pioneer and is capable of many tasks, however I use it to assist me in the monitoring of field health.  Some of the fields I’m responsible for scouting are well over 100 acres.  If one of these fields are an area of poor health, I would have a slim chance of realizing it unless I walked through it all, which would take all day.  I don’t know the exact details of how Encirca works but it utilizes satellite images that are taken daily and maps the health of your field.  This is useful because instead of aimlessly walking through the fields, I can look at my phone, see where the problem spots are, and make sure to check those specific areas when out scouting.  With as wet as it was earlier this summer, many of the “low health” areas are spots that were wet or the crop simply drowned out.  The one downside of Encirca is that on cloudy days (which there have been a lot of), the satellite can’t get a clear image of the fields so you have to rely of day from previous days.

The second app, Granular is one that all the employees on the farm have and it is where we either record work that we have done, or are assigned work by someone else. I se it to record all my notes from scouting and add pictures when necessary. My boss can later review my notes and we can talk about treatment options if there is an insect or weed problem that needs addressing.  A few weeks ago, I also used Granular to assign work orders to our sprayer operator for fields that were particularly weedy and needed to be sprayed sooner than later.

 

 

Week Seven: Drones!

Quantix drone

In this image, Greg is inserting a fresh battery for a new round of flights. Quantix drones can survey up to 400 acres on a single 45 minute flight.

 

This week I got to see even more drone action in the field. Greg and I drove up to several farms and he walked me through the flight process in more detail. Greg is a FAA certified drone pilot and has been troubleshooting with our current drone lineup for quite a while. He has run into some issues with one of the drones, Quantix, which is almost too automated for its own good. The Quantix take-off and landing processes are fully automated, which means that the drone not only pilots itself but also sets its own take-off and landing flight path. Although the drone has a unique method of vertical take-off and landing, it is still at a relatively low altitude when it begins its second round of fixed-wing style flight while increasing or decreasing altitude. Quantix drones are considered “hybrids,” in that they combine the agile helicopter-style flight of quad-copters as well as the speedy and highly efficient cruising motion of fixed-wing planes.

 

Although it would normally be a big perk to have the pre-scan and post-scan flight paths automatically generated, the tree lines in New York State make this style of take-off and landing very risky. It would be too battery draining for the drone to use vertical take-off to reach its final cruising altitude, so Greg has been looking for new ways to manually alter the pre-scan and post-scan flight paths. These include selecting new initial take-off and landing zones for the drone, as well as modifying the area that the drone is set to actually scan in order to force a new overall flight path. Although it would probably be incredibly easy to use in my home state of Iowa, the massive tree lines and diverse landscapes of New York State provide an array of challenges for this drone.

Painting the Roses Red, Painting the Apple Trees White

Hey y’all, welcome back to the blog! This week, I wanted to take a moment and discuss/write a list of all of the odds and ends kind of jobs to keep the FREC orchards running.

1.) The first task I wanted to talk about was tree training. It was the task that I feel like we did the most of throughout different parts of the orchard. Tree training was used to keep the trees growing in the correct direction. We would use a variety of different tools to get the trees growing correctly. This usually included tree tension clips, CEP tape, a thinner red tape, electrical tape, bamboo sticks, pruners, and a lot of patience. I will include a photo below of Megan and I tree training. This was also one of my favorite tasks because you could always find cool looking bugs or birds nests with eggs (and sometimes baby birds!).

2.) The next task was a real cow and probably one of my least favorite tasks: pruning trees. This was especially awful in a large block of peaches because it felt like it would never end. The trees were five years old and had been trained into a quad-V formation, meaning they had four scaffolds tied to trellis wires. The trees needed to be pruned on both side of the row because of this type of training and because they were tall, they needed done on both the tops and the bottoms. Additionally, the trellis wire was plastic, not metal wire, so it was very easy to cut and break with your pruners. Unfortunately, I did that twice.

3.) The third task that I did was also quite painful and also in the same aforementioned block of peaches. I had to take soil samples of the different plots of trees. There were seventy five plots of five trees each and I need to get a soil sample from each tree. That’s 375 samples, 375 holes in the ground. Additionally, the soil probe is ineffective in the soil we had because it was so rocky, so I had to use a shovel. Ever since I did that, I have compared every other task we did to that one.

4.) This next task was pretty fun. I was helping work on a chemical thinning experiment and I had to take the sample apples and collect data on them. I had roughly seventy apples where I had to weigh them and take their diameter. Then, I had to cut each one open and count their viable seeds. I was given a very large knife, a very small knife, and an envelope opener to complete the task. I had fun! I have attached a picture below.

5.) One of the other fun things I got to do was paint our new baby trees! We have a new block of apples of roughly 1300 Premier Honey Crisp apples and 400 EverCrisp apples. They are painted white to protect from herbicide and sun scald. We used outdoor latex paint and painted them all in a day. In addition to this, all tenth trees are painted specific colors so when you are out there it is easier to know what tree you are on. For example, every tenth tree is yellow, but the 30th is painted red, 60th is blue, 90th is purple, and 120th is orange. Any tree that is out of the study due to illness or replacement is lime green. This was done in more than the new apple trees, but also in any block that needed it. Below is a not-so-great picture of the newly painted baby trees.

6.) The next job is repainting the graft union of top-worked treed with sealant. We have a few rows of trees that have been top-worked, meaning that they grew an apple tree normally, then decided they wanted them to be a different variety, but wanted a quick turn around. In order to do this, they cut off the tree where the scion joined the rootstock and grafted new healthy buds of a different variety there. to ensure they stay, they wrap it in grafting tape and come back later with an antibacterial sealant to ensure it stays. The sealant need reapplied about once a year, so this year Megan and I got the joy of reapplying it. The sealant had the color of Kraft mac and cheese, and an absolutely awful smell. Unfortunately technology has not advanced to allow you all to smell it, but I will post a picture of it below.

7.) Another task that we did a lot of was thinning apples and peaches. However, one experience really stuck out to me, which was thinning very large Hone Crisp apples. Because they were so large, you would pull one off to thin a cluster down from a triple to a double and all three of the apples would fall off. Pulling just one off without all of the rest coming with it was almost an art form. I did find this one apple that had seen all kinds of challenges, but still managed to grow. It had grown around the clip that held the tree to the wire, around the tree itself, and around the wire. I’ll put pictures below.

 

There are dozens of other tasks to keep the orchard in tip-top shape, but I won’t bore you with the details. In the next blog post, I am excited to write about some other experiments I helped with!

Week Six: Soil Sampling

This week I got to help out with some soil sampling in corn fields. NMSP is working with farmers to do trials on N-rich strips, which are sections of a field that are given so much pre-plant nitrogen that sidedressing is unlikely to be necessary. These plots help farmers to estimate how much nitrogen they need in certain areas and guess whether or not larger applications of nitrogen would make sense economically across certain management zones.

Field technicians use soil probes to take core samples from two soil depths, 8″ and 12″. The 8″ samples are used for general soil fertility tests, while the 12″ samples are tested in-house for soil nitrate levels. Although the 12″ cores can be very difficult to take in rocky soils, it’s important for researchers to know how much nitrate is present throughout the entire rooting zone.

Bagged soil sample

NMSP uses a double bagging method to keep soil samples secured and organized. The outer bag contains a small ID tag with replication and treatment info, along with the inner bag which contains the actual sample.

Soil samples in a dryer

The bags are opened up back in the lab, where the soil samples and ID tags are placed into individual cups for further processing. Soil cups are then loaded into the 50 °C dryer in order to remove most soil moisture. Processing wet soils would be very messy and lead to less reliable data.

Edgewood Farms, LLC Internship

Hello, my name is Bryce Schuster and I am a soon to be senior, studying agricultural science.  This summer I am completing my internship at Edgewood Farms, LLC in Groveland, New York.  Edgewood Farms is primarily a crop farm, but also operates a small feedlot, and is an authorized reseller of drainage tile, bunk covers and bags, fencing supplies and agricultural GPS systems.  The main crops grown are corn and soybeans, however they also grow wheat, green beans, kidney beans, and black beans.  The mission at Edgewood Farms, LLC is to provide quality products and service to their customers, while maintaining the integrity of the land, animals and environmental resources.  My duties this summer consist mostly of crop scouting, tissue sampling, and field agronomic problem-solving.

This spring and the beginning of summer have made farming difficult to say the least here in Western New York.  It has rained constantly and been cooler than normal until a couple of weeks ago.  When I started the internship at the end of May, corn planting was just getting under way.  This meant all hands-on deck to get fields prepped and seed in the ground.  Without any crops for me to scout this meant I also got the opportunity to assist with field work in equipment that is much larger than I am used to on my farm.

My first week on the job consisted of learning the names and location of over 200 fields, making up almost 4,000 acres, spread over 3 townships; and running a Case IH 9180 with a chisel plow to fill in ruts made by the farms sprayer that was applying pre-emerge herbicide.  Edgewood Farms has made the transition to an almost entirely strip tillage or no-till cropping system so it is rare to see conventional tillage performed, such as chisel plowing.  However, when last fall and this spring saw excessive rainfall, it is inevitable that a 35,000 lbs. sprayer with narrow tires is going to sink into the ground more than is ideal.  I also got the chance to use their 40-foot-wide roller to roll fields that are planted to beans, making the ground as flat as possible to optimize yield by allowing the combine header to be run closer to the ground without risking damage by picking up a rock.

Soil erosion on a conventionally tilled corn field.

Now that crops are finally starting to germinate and emerge, I can begin my scouting.  When the crops were still in the VE stage my main focus was on taking stand counts and checking for insect damage.  With all the moisture, one problem associated with strip or no-till cropping systems became apparent.  While the residue on the ground from last years crop is good for soil moisture retention in dry periods and weed suppression, it also creates a great environment for slugs.  I never knew slugs could do so much damage to crops and unfortunately it is not an easy problem to control.  Slug bait is extremely expensive so purchasing enough to treat every field is not practical.  The best way to end the problem is for things to dry out a little bit.  I am looking forward to how the summer progresses and what knew things I can learn!

Slug damage.

Week Five: NDVI for Nitrogen Management

This week was very exciting! I continued working with R and several yield cleaning projects, but also got to join Greg for a couple of rounds of field work. This meant getting to see two of NMSP’s drones complete NDVI scans of corn fields. NDVI scans are able to measure the vigor of plants in the field, either to estimate yield or to help farmers more accurately place sidedress fertilizer. The latter seems very interesting but also very challenging. NDVI works on a scale of 0 to 1, with 1 being very green and 0 being not green at all.

Quantix drone

Drones are the quickest way for farmers to accurately take NDVI readings over a full field.

 

The greener sections of the field are assumed to not be nitrogen deficient, and the less green sections are given extra nitrogen to address lower vigor. However, lower vigor could also be due to other factors like a wet spot in the field or a deficiency of nutrients other than nitrogen. As precision ag technology continues to evolve, it will be cool to see how companies and farmers address these issues. Looking for patterns in individual leaves is one solution, but it would require very high resolution cameras and advanced imagery technology. I will be excited to learn more about this quickly moving ag sector as the summer goes on!
